Title: Crankshaft grinding machine
IPC: B24B5/42
Filed: 1953-10-05
Abstract: 729,890. Grinding crankshafts. TEISEN, M. R. G. Oct. 5, 1953 [Oct. 11, 1952], No. 27329/53. Class 60. A crankshaft grinding machine comprises a frame 1, Fig. 1, a grinding wheel 10 mounted for rotation about a stationary axis, means for supporting a crankshaft 24 for rotation about its normal axis of rotation, means for guiding the support. ing means so as to permit transverse movement in any direction of the normal axis of the crankshaft, and means for keeping a crank pin to be ground in correct working position relative to the grinding wheel. The grinding wheel is supported by a slide and connected by a V-belt drive with a motor 13. An arm 15 angularly adjustable by a worm gear 17 is also supported by the slide and is provided with a notch 16 which holds the crank pin to be ground in fixed relation to the grinding wheel. A chuck 25 and a centre support and drive the crankshaft about the axis of the pin to be treated and are mounted on a framework which permits them to move in a circular path transverse to the crankshaft axis. This framework consists of two brackets 22, 23 secured to a tubular member 21 rotatably mounted between a pair of arms 18, 19 pivotally connected to columns 2, 3 on the machine frame. In setting up the machine, the weight of the crankshaft is first balanced about the axis of the member 21 and then balanced about the pivots of the arms 18, 19. This is accomplished automatically by a valve 32, Fig. 4, which may be connected to a lever 28 coupled to a counterbalance arm 26 and the arms 18, 19 by a spring 30 and hinged rods 27, 29. When the crankshaft is first mounted in the machine, the arms 18, 19, the lever 28 and the valve 32 move counterclockwise so that an arm 38 secured to the latter urges a piston 40 towards the bottom of a cylinder 41. The oil pump of the machine is now connected to a duct 42 to lift the piston until a duct 48 therein registers with a duct 45 to permit oil to pass to a chamber 47 and compress the spring 30. When the oil pressure reaches a value corresponding to balance about the axis of the member 21, the piston is further displaced to stop the oil supply to the chamber 47 and to move the valve 32 to connect the cooling water pump of the machine to a drum 20 rigidly connected to the arms 18, 19. Once the drum 20 has received enough water to balance the weight of the crankshaft about the pivots of the arms 18, 19, the latter swing clockwise and hence cause the valve 32 to cut off the water supply to the drum 20. The valve 32 is locked to the machine frame during grinding and is operated manually to empty the drum 20 and the chamber 47. The journal portions of the crankshaft may be ground by locking the arms 18, 19 and the member 21.

Title: Improvements in and relating to valve gears for direct-acting reciprocating steam engines
IPC: F01L29/06
Filed: 1945-10-25
Abstract: 602,058. Steam-engine valves. WERKSPOOR, N. V. Oct. 25, 1945, No. 38139. Convention date, Dec. 31, 1941. [Class 122 (ii)] In a valve gear for a direct-acting reciprocating steam engine comprising a main slide valve 2 actuated by steam and an auxiliary slide valve 3 actuated by the piston, the auxiliary valve being accommodated in an individual valve chest and adapted by its reciprocation to control the admission of steam to the main slide valve, the auxiliary slide valve is reciprocated by the main valve in a direction at right angles to that wherein it is moved by the piston in such a manner as to close the exhaust of the main slide valve prior to the latter reaching the end of its stroke. Reciprocation of the main valve 2 and its associated pin 14 imparts motion to an arm 15 to rotate the valve 3. When the piston has completed its stroke in one direction, the valves are in the position shown. Steam flows from inlet chamber 5 into duct 9, passage 11 and duct 7 to move the piston in the other direction, steam being exhausted through duct 8 and recess 13 into the exhaust chamber 6. The piston moves the valve 3 to the right until passages 17 and 19 are placed in communication by the recess 21 with the exhaust chamber 6, and passages 18 and 20 are connected with the inlet chamber 5, whereby valve 2 is moved. During this movement the pin 14 and arm 15 rotate valve 3 to cut-off recess 21 from passage 17 and thereby close the exhaust at the end of valve 2. The steam not exhausted is then compressed so as to cushion the valve. The movement of the main valve 2 reverses the inlet and exhaust to the piston which then moves back again and the cycle is repeated through the other set of passages.
